Patent DE-3414671-A1 (DE)
Title: Adhesive tape shearing device
Inventor: BOHLEBER PETER PAUL FRITZ
IPC: B26F3/08
Filed: 1984-04-18
Abstract: Blades for cutting plastic adhesive tapes have only a very short life, since the adhesive tapes always strike the edge of the blade at the same point. If it is neglected to exchange the blade promptly, distortion of the separating cut can result or the plastics adhesive tape can tear, which can lead to rejects in the case of coating processes, in particular in the case of electroplating, where such plastics adhesive tapes serve to cover parts of the workpiece which are not to be coated. In order to prevent this, the invention proposes to heat the blade via a heat source up to maximally the melting temperature of the plastic. This heated blade heats the plastic of the plastics adhesive tape to its softening temperature, thus preserving the blade edge and resulting in a long life of the blade. <IMAGE>

Patent DE-3500197-A1 (DE)
Title: Yarn designer
Inventor: ESSER ANNA MARIA
IPC: D06B11/00
Filed: 1985-01-03
Abstract: The yarn designer is an entirely novel way of knitting a pattern. The construction and opereation of the yarn designer can be seen from the appended drawing. The woollen yarn is printed with a dye and provided with knobs, which allows any type of pattern to be knitted using only one piece of yarn. This is made possible by computer technology and by the way that the yarn designer is constructed. Counting stitches or the pattern is dispensed with since the stitch size, which is determined by the wax knobs, excludes a pattern shift.   One stitch is knitted, resulting in a knob on the left and right sides, so that it can be seen, or felt by blind people, that the distance between 2 knobs is one stitch. Decreasing size of a piece is marked by a double knob, so that the decreases involved in the knitting of sleeve and neck openings is simplified. The knitting stitches are: one row knit, one row purl. After the individual pieces of the jumper (pullover) have been finished, they are soaked in a wool detergent to remove the (water-soluble) wax knobs. When the individual pieces have dried, they are steamed and subsequently sewn together to finish the patterned jumper (pullover).

Patent DE-3513666-A1 (DE)
Title: Industrial door
Inventor: REJC GABRIJEL DIPL ING
IPC: E05F15/605
Filed: 1985-04-16
Abstract: An industrial door, especially in the form of a folding or swing door, has a drive unit (10) which is arranged in the manner of a power cylinder between a fixed support point (20) and a movable engagement point (22). The drive unit has an electric motor (12), especially in the form of a rotating-field magnet, and a threaded-spindle drive (14) driven by the latter and having a threaded spindle (48) and a spindle nut (56). The threaded spindle (48) possesses a thread pitch which prevents a self-locking of the threaded-spindle drive (14). This ensures that, in cooperation with the special characteristics of the rotating-field magnet motor, the industrial door behaves in the same way as a non-driven swing door, that is to say a jamming or forced change of the movement of the door wing does not cause any damage to the threaded-spindle drive (14) or to the electric motor (12). <IMAGE>
Patent DE-3513800-A1 (DE)
Title: Cobbing separator with baffle plate
Inventor: SPRENGER HEINER
IPC: B03C1/14
Filed: 1985-04-17
Abstract: A baffle plate around a drum (1) in the region of the magnet (2) of a cobbing separator has the effect that particles flying away are deflected back into the bed and, as a result, the probability increases that less magnetisable particles remain behind in the non-extracted fraction. Loosening members (7) on the inside of the baffle plate (5) have the effect that non-magnetisable particles can leave the bed formed directly on the surface of the drum more readily. With the apparatus it is possible, inter alia, to increase throughput while maintaining the same precision of separation. With such an apparatus, it is also possible to separate the magnetisable fraction or the non-magnetisable fraction a second time during the same operation, which has the consequence of a particularly pure fraction. <IMAGE>

Patent DE-3524729-A1 (DE)
Inventor: DIETRICH WALTER
IPC: F25J1/02
Filed: 1985-07-11
Abstract: The invention relates to a method and apparatus for the purification and recirculation of gases which are fed to a plant for the production of metal powder or for compacting metal powder at elevated pressures. The operating gas exits the plant at a lower pressure and is conveyed in a closed loop, in which filters are provided for the mechanical and/or chemical purification of the gases as well as means for increasing the pressure of the purified gas. The repressurization of the operating gas is carried out economically by liquefying the operating gas leaving the plant after purification by the application of liquid nitrogen, then feeding the liquefied gas to an evaporator via a high-pressure pump, and finally returning the operating gas to the plant in a pressurized gaseous phase.

Title: Process for the production of a large rubbish container and a container produced by this process
Inventor: ABATE GUIDO
IPC: B65D88/02
Filed: 1985-07-30
Abstract: The present invention relates to a process for the production of a large rubbish container which consists in that a flat, plate-shaped element of sheet metal is stamped, forming a central bottom surface flanked by two adjoining zones which run in corresponding fashion into a forward and a rearward zone. At the longitudinal edges, the abovementioned zones have legs which delimit a first bent part, which ends in a second bent part. The stamped plate-shaped element is then bent at the separation lines between the various zones to form the forward zone and the rearward zone and is provided with an extension which extends obliquely upwards. The first bent part of the legs is thus bent, thereby producing an extension of the upper edges of the front side and of the other upper zone, and the second bent part is bent in order to obtain a fixing edge for the sides. Finally, the sides are fixed to this edge to obtain a container into which a similar container can easily be stacked.
